Unrecognised charge

2 years ago we purchased a joomla extension and the transaction came through this site.

In November 2020 a charge came up from this site for £46.05. we have no idea what it’s for and I note the Joomla extension is no longer available.

The charge is the biggest problem right now. There doesn’t seem to be any way to contact you or raise this. We have had no invoice and no account activity is showing.

Can somebody help?
